Massachusetts 93A Demand Letter Requirements

Massachusetts 93A demand letter requirements come from Section 9(3) of General Laws Chapter 93A: before you sue a business for an unfair or deceptive practice, you must send a written letter, at least 30 days before filing, that identifies you, reasonably describes the practice you’re complaining about, and explains the injury you suffered.¹ Skip the letter and a court will dismiss your case. Get it right and you preserve access to double or triple damages plus attorney’s fees.

What the Letter Must Contain

Section 9(3) sets three required elements. The letter identifies the claimant, reasonably describes the unfair or deceptive act or practice, and describes the injury suffered.¹ There is no mandated format. What the statute requires is enough detail that the recipient understands what they allegedly did wrong and what harm resulted.

In practice, an effective letter goes one step further and states the specific relief you want: a dollar amount, a refund, a repair, or some combination. The statute technically requires only a description of the injury and the practice, but a letter that quantifies the harm and names a remedy is what lets the business evaluate whether to settle. Vague letters that describe wrongdoing without quantifying it rarely produce a response.

Be specific about dates, transactions, and amounts. Attach supporting documents — receipts, contracts, correspondence, photographs. A letter that reads like it was written by someone who has already organized their evidence signals that you are prepared to litigate if the business does not respond seriously.

How to Send It

The statute says the letter must be “mailed or delivered” to the prospective respondent.¹ Certified mail is not legally required. The Massachusetts Attorney General’s office recommends sending the letter by certified mail with return receipt requested so you have proof of delivery.² If the case reaches court, you will need to show the letter was sent and when. The green return receipt card is the simplest way to prove that.

When a Demand Letter Is Not Required

Two situations excuse the letter. You do not need to send one if you are asserting a 93A claim as a counterclaim or cross-claim in an existing lawsuit. You also do not need to send one if the business does not maintain a place of business or keep assets in Massachusetts. In that second situation, the business can still invoke the settlement-offer protections described below by making a written offer and paying the tendered amount into court after being served.¹

Section 9 governs consumer claims. Businesses suing other businesses under Section 11 do not send demand letters at all and can file suit directly.³ If you are pursuing a business-to-business claim, the demand letter rule does not apply to you.

Describing the Unfair or Deceptive Practice

To meet the “reasonably describes” requirement, you need to know what qualifies. Section 2 of Chapter 93A declares that unfair methods of competition and unfair or deceptive acts in trade or commerce are unlawful, and directs courts to follow interpretations that federal courts and the Federal Trade Commission have given to Section 5(a)(1) of the FTC Act.⁴ The Attorney General has issued regulations under Section 2(c) that define specific unfair practices, and those appear in Title 940 of the Code of Massachusetts Regulations covering areas like debt collection, automobile sales, and home improvement contracts.

Common practices that generate demand letters include:

False advertising, such as misrepresenting a product’s quality, origin, or capabilities.
Failure to disclose material information, such as omitting fees, risks, or contract terms that would affect a purchasing decision.
Hidden fees and deceptive contract terms buried in fine print.
Unfair insurance claims handling: delaying, denying, or lowballing claims without legitimate justification.

Because the statute is written broadly, courts have applied it to conduct that does not fit traditional fraud categories. A practice can be “unfair” even when it is not technically “deceptive.” Aggressive collection tactics or exploiting a consumer’s lack of bargaining power can qualify.

The 30-Day Response Window

Once the business receives your letter, it has 30 days to respond. Three things typically happen.

The business agrees to your demands in full or negotiates a settlement. Document any agreement in writing.

The business makes a written settlement offer that falls short of what you asked for. This is the moment where a 93A case is often won or lost, and it is discussed in its own section below.

The business ignores the letter or sends a response that offers no meaningful relief. After 30 days pass from mailing or delivery, you are free to file suit. A non-response or bad-faith refusal actually strengthens your position. The statute treats a refusal to grant relief “made in bad faith with knowledge or reason to know” that the practice violated Section 2 the same way it treats a willful violation, which opens the door to multiple damages.¹

Why the Amount You Demand Matters: The Reasonable Offer Defense

This provision is the reason your letter should state a realistic dollar figure tied to your actual losses. If the business responds within 30 days with a written settlement offer, and you reject it, the business can file that offer with the court along with an affidavit about the rejection. If the court finds the offer was reasonable in relation to your actual injury, your recovery is limited to the amount offered. No multiplier. No enhanced damages.¹

The court must also deny attorney’s fees and costs that accrued after you rejected a reasonable offer.¹ Because most attorney’s fees accumulate during litigation rather than during the demand phase, this can wipe out most of a fee award. Evaluate any offer carefully before rejecting it. If the business offers something close to your actual out-of-pocket losses, rejecting it in the hope of getting treble damages at trial is a gamble worth discussing with a lawyer.

Damages the Letter Puts on the Table

The remedy you request should reflect what the statute allows you to recover. If a court finds a violation, the minimum award is $25 or actual damages, whichever is greater. If the court finds the violation was willful or knowing, or that the business refused to settle in bad faith, it must multiply damages by at least two and can go up to three times actual damages.¹ The multiplier is mandatory once the court finds willfulness, not discretionary.

A prevailing consumer also recovers reasonable attorney’s fees and court costs regardless of the amount in controversy.¹ Courts can also grant injunctive relief, ordering the business to stop the offending practice. When you draft the letter, you can ask for actual damages, multiplied damages if the conduct is willful, fees, and any injunctive relief that fits the situation.

Deadline to Send the Letter

You have four years from when the cause of action accrues to bring a 93A claim, under M.G.L. Chapter 260, Section 5A.⁵ The clock generally starts when the unfair or deceptive act occurs, though Massachusetts courts have applied a discovery rule in some circumstances, meaning the clock may start when you knew or should have known about the violation.

Because the letter must go out at least 30 days before you file suit, plan backward from the four-year date. If you are close to the deadline, send the letter immediately. Waiting until the last month and then discovering the business wants time to respond can push your suit past the limitations period.
